KAPS for many years have produced Dog Gearbox Kits for Subaru, Mitsubishi and other makes for competition use… now a fully sequential gear changing unit is available. Using the similar Dog ring engagement and coupled with a custom gear selector drum, seamless gear changes can be made!

KAPS have supplied Sequential gearboxes to Japan, USA, Belgium, Czech Republic and Australia. Approximately 6 units are in active competition use and their primary applications have been in Rally Cross and Rallying. One Rally Cross car has been noted of running a KAPS Sequential Gearbox with 780nm torque and 500HP without problems.

KAPS produce the sequential gearbox from KAPS custom parts and Standard Series parts (e.g.: Subaru Standard 6 Speed), so a donor gearbox is required for assembly.

EPS Cutting System cuts the fuel injection to seamless make full throttle gear changes possible (without use of the clutch). Cutting times can be varied for each gear on the EPS computer via a laptop computer (USB connection). Typically 1st gear 125ms thru to 6th gear 80ms cutting times. Shifting lever force can be modified as well.

That kit looks ok Ramon, I am not aware of any other being manufactured anywhere.

Like I said I would love for us to do it, but we are just too busy at the moment. Honestly for the pain and heartache that will inevitably be involved I think we would only do it as a stand alone gearbox. The KAPS one looks like it uses standard diffs and some of the original cases, so thats where the problem is. They break and we get blamed.

We are now doing sequential kits for Porsche's, Lambo's and Astins, this works because they are all really good gearboxes to start with.

Japanese car companies have NO idea about designing strong, well thought out boxes. They are all massively underated for what their cars can achieve. The new suby six speed if HUGE yet still no where near strong enough. It is not as strong as it is heavy if you ctach my drift. Typical.

So again at the moment it is a definate no. Check again in a couple of years when things may have settled down.

well not wanted, but we were discussing how it would work. do to you require a auto box and then customize electronic controls, or a unique gearbox as this suggests.

anybody in the know?

Think the WRC basicaly use the above design as far as the gear selector leaver just that the paddles operate an actuator connected to the leaver. No software etc to make the shitfer work just a direct electrical connection. As for the box no idea on what is involved in that.

Have a look at the next in car shots you see. Would be the easiest way to get a paddle shit I woud imagine.

paddle-shit vehicles exist already. minis, skylines, at the lower spectrum of the cost.

these all appear to be on 'seqential automatic' gearboxes. to there must be a low cost option out there. otherwise people would be ripping out skyline boxes and forcing them to fit in other vehicles...
